Single Sided Lapping of an Electrical Component

The customer provides a copper disk with a thickness that varies by +/- 0.002” from the nominal. The parts are flat within 0.004”, parallel within 0.001”, and have a surface finish that measures 63 Ra.

Utilizing one of our single-sided machines and free abrasive machining, we delivered parts with a thickness of +/- 0.003”, flatness within +/- 0.0005”, parallelism within +/- 0.0005”, and a surface finish of 16 Ra or better.

The customer was very pleased with our processing as it improved the performance of their electrical component.
